Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486868, here are decompositions:

11 + 2147486857 = 2147486868
17 + 2147486851 = 2147486868
19 + 2147486849 = 2147486868
41 + 2147486827 = 2147486868
127 + 2147486741 = 2147486868
157 + 2147486711 = 2147486868
179 + 2147486689 = 2147486868
199 + 2147486669 = 2147486868

Showing the first eight; more decompositions exist.

IPv4 address
